Testing Images With Imatest

Using Imatest 4.5, the checkerboard region can be analyzed using the Checkerboard module. The dot pattern analysis module has been available since 2011 Release 3.8.

For older versions of Imatest, you can use the distortion module to calculate distortion from the checkerboard, but this is not as resistant to fisheye distortion as what is available with the Checkerboard module of Imatest 4.5.
